32NFR

32NFR delivers incredible . It comes together with other speaker models as the next generation of our full-range drivers. Well balanced frequency response from LF to HF, low harmonic distortion, and on top of that all packed in a lightweight and compact mechanical structure.
The driver was designed around neodymium ring magnet. Magnetic circuit delivers the highest level of performance, with minimum modulation distortion.
The cone and surround were newly designed and optimized specifically for this model. Progressive roll surround further improves the frequency response.
Our newly designed basket with typical REDCATT visual aspects sports front and rear gaskets, thus the driver can be easily mounted on both sides of baffle. Large basket openings minimize turbulences and air noise. Space bellow spider is also vented. This further improves the temperature stability of this model. The mounting surface has a flange all around, feature that greatly improves mechanical rigidity.

The 32NFRX8-463A is a 3-inch full-range driver featuring a neodymium ring magnetic circuit and a high-force motor (Bl = 5.35 T.m), producing the highest sensitivity (90.99 dB / 2.83V/1m, 89.37 dB / 1W/1m) and maximum SPL (104.1 dB at 30W AES) of the seven-variant full-range driver family by a substantial margin. The carbon fiber reinforced paper cone uses a progressive roll geometry with an optimised NBR rubber surround, driven by a ~19mm CCAW voice coil on a Kapton former. The steel basket features an all-around front flange, front and rear gaskets enabling both front- and rear-mounting, and a vented spider cavity for improved thermal stability. Qts = 0.32 reflects a low Qts, high motor strength design optimised to maintain consistent performance at high drive levels - and uniquely within the full-range family, this driver requires vented (bass-reflex) enclosures, not free-air mounting.

- 4 L / 115 Hz - compact column driver section; port ~196 mm physical; 0.65 m/s
- 6 L / 95 Hz - standard column or 2-way PA; port ~191 mm physical; 0.54 m/s
- 10 L / 75 Hz - extended LF for large column or standalone system; port ~181 mm; 0.42 m/s

For sub-assisted column installations, sealed enclosures of 130-294 mL (Qtc=0.707-1.00, f-3dB 261-290 Hz) provide very compact and practical rear cavities for slim column form factors where a separate subwoofer covers the bass band. Amplification of 30-60W from an 8ohm output is appropriate. The voice coil inductance Le = 0.20 mH is the highest in the family, placing the inductance rolloff onset at 4,374 Hz - within the audio band; DSP treble correction above 4 kHz is recommended for tweeter-less full-range use. Cone beaming onset at 3,370 Hz is also the earliest in the family. In column array applications, the 82.5mm driver OD limits coherent vertical directivity to approximately 2.1 kHz. A Zobel network (5.5ohm + 6.6 uF in series across driver terminals) is recommended for passive crossover designs, and is particularly important for this driver given its higher Le. The 32NFRX8-463A is suited for high-efficiency professional column speaker systems requiring maximum SPL from a 3-inch format with proper vented bass alignment; two-way PA and installed sound systems where its high sensitivity enables high output at moderate amplifier power; multi-way arrays using the driver's midrange efficiency with bass coverage from dedicated woofers or subwoofers; and any application where 104+ dB SPL from a compact full-range driver is the principal design objective.
